CAB LE-TRAMWAY.

SPECIFICATION forming part of Letters Patent No. 645,314, dated March 13, 1900.

r Application led May 6, 1899. Serial No. 715,875. (No model.)

To all whom, t may concern:

Be it known that I, WILLIAM DUSEDAU, a

citizen of the United States, residing at New York, {Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Cable-Tramways, of which the following is a specification.

My present invention pertains to improvements in elevated rope tramways, the construction and advantages of which will be hereinafter set forth, reference being had to the accompanying drawings, in which- Figure lis an end elevation of the carriage, the bucket or collar, and their appurtenant parts; Fig. 2, a front face view of the same; Fig. 3, a diagrammatic View showing the relation of the carrying-cable and the tractionrope; Fig. 4, a vertical sectional view taken centrally through the carriage and the gripping mechanism; Fig. 5, a face view of the gripping mechanism; Fig. 6, a sectional view on the line l 1 of Fig. 4.; Fig. 7, an elevation of the rear face of the grip-carrying frame; Fig. 8, a side elevation of the carriage; and Fig. 9, a horizontal sectional view of the carriage, taken through the axes of the wheels.

One object of my invention is to provide a simple, light, and at the same time a strong and efficient apparatus.

A further object is to place the carryingcable and the traction rope or cable in such relation to each other that the traction-cable will in a measure serve to support the load, and thus relieve the carrying-cable of a portion of the strain.

Other advantages are present and will appear in the following description.

Referring to the drawings, A denotes the carrying-cable, and B the traction rope or cable. Any suitable support, such as C, may be employed for the carrying-cable, said support being mounted upon a suitable bracket, which in turn is mounted upon the framework or other support E. r

In the lower end of the bracket I mount an axle, upon which is journaled a sheave F for supporting the traction-cable B. As will be noted more particularly upon reference to Figs. 1 and 4, the cables are not in vertical alinement, and for this reason a large supporting-sheave may be employed and at the same time the cablesmay be-kept closely t0- gether-a point of material advantage. This feature of having the cables out of line also permits them to swing vertically without becoming entangled.

The carriage G for carrying the various parts of the apparatus is shown in detail in Figs. 4, 8, and 9. It comprises a single casting provided with arms H, between which at each end are mounted wheels I. As will be seen upon reference to Fig. 9, the hubs of the Wheels are hollow and a perforated sleeve or bushing J passes therethrough, while an axle K passes through the bushing and is secured at its ends in the arms H.

To give the proper strength to the carriage, it is provided with a cross-web L, below which is formed or cored out in the process of casting a journal-bearing M. This construction of the carriage is not only simple, but is light and strong and affords a support for each end of the wheel-axles K, which of course is not present when the wheel is mounted outside or to one side of the carriage.

N denotes the outer grip frame or casing secured upon a hanger pin or axle O, which is journaled in the bearing M. Said frame is formed with arelatively-large transverse opening, in which is rotatably mounted a shell or casing P forholding the gripping mechanism. Frame N is provided with two oppositely-disposed grooves or ways Q, while the shell or casing P has formed upon its rear face two lugs R and upon its forward face a collar or flange S. The lugs R are of such dimension that they will pass through the channels or ways Q when said lugs are brought into alinement therewith, and in assembling the parts the shell or casing is passed through the opening in the frame N and given a quarter-turn, collar SA bearing against the forward face of the frame. N, while the lugs, which are passed through the channels or ways Q, bear upon the rearl face of said frame. While the parts are thus held against endwise movement, they may nevertheless be rotated one in relation to the other without fear of separation, except when the lugs R come opposite the ways or channels Q. This cannot take place, however, when the whole mechanism is assembled.v The gripping mechanism, which is carried by said rotatable shell or casing P, comprises two jaws T and U, actuated by le- IOO . also to take up any wear in the parts.

vers V and W. Said levers are mounted upon a pin X,carried bya forwardly-projecting portion of the shell 0r casing P. The rear ends of said levers V and V are pivotally connected to links a b, which in turn are connected at their inner ends to a pin 1c, carried by a forward extension cl of the cross-head c. The pivotal connection between the ends of the levers V and W and the links a and b is made by an eccentric-shaped pin, which may be rotated when desired to vary the adjust-ment of the jaws toward and from each other and Such connection is shown in my previous patent, No. 611,570, dated September 27, 1898.

Cross-head e has connected to each end thereof suitable guide-rods f, which work in ways formed in the shell or casing P. (See Fig. 6.) To vary the adjustment of these guiderods relatively to the head, I provide each rod at its outer end with an enlarged threaded section g, which takes in a suitable thread formed in the cross-head. By turning said rods by means of a wrench applied to their outer squared ends they may be turned in or out, as desired, thereby varying the position of the pivot-pin c with relation to the pivotal connection of the levers V and lV with the links ct b.

Cross-head c is provided with an upstanding arm or axle t', upon which are journaled or mounted two rollers j and l7c, said rollers standing in the path of suitable strikingplates which serve to actuate the cross-head and open or close the jaws, according to which plate said rollers come in contact with. The jaws are shown in their closed position in Fig. 4, wherein it will be noted that the levers a and b, which form a toggle, are in alinement, or substantially so, and the centers of the pivotal connections are also in practical alineinent, so that the jaws will be held closed. When the rollers j k come in Contact with the striking-plate which serves to open the jaws, the cross-head will be moved outwardly, drawing the pin c in the same direction and breaking the toggle, whereby the levers V and WV will approach each other and the gates be opened. To assist in the quick release of the gripping members, I may employ a spring Z, Fig. 1.1., which so soon as the toggle is broken serves to force lever V down and thereby to open the jaws. The forward extension of the inner shell or member P has mounted in each end thereof suitable guide-rollers m, which bear directly upon the traction rope or cable, as is clearly shown in Fig. 5. Secured to and depending from the outer frame N are suitable hangers fn, as will be seen upon reference to Fig. 1. Said hangers are given a slight bend, so as to bring the bucket which is carried thereby directly beneath the carryingcable. These arms carry the bucket or load only, and for the reason that they are carried by the frame or casing N they are not sub jected to any strains from the traction-rope. Any vertical strain placed upon the tractionrope by reason of the load will either serve to carry part of the load or the strain will be transmitted directly from the grip to the carri age. The traction-rope serves .to carry part of the load at points intermediate the towers, for the reason that it is tightened in the same or practically the same proportion as the carrying-cable, and the traction-rope is at any point between the towers deflected in practically the same manner as the carrying-cable, and, further, the traction-rope is only lifted slightly from the supporting-sheave while the car is passing a tower. l

It will be noted from the foregoing description that the connection of the parts between the carriage and the gripping mechanism adapted to grasp the traction-rope is fixed so far as any direct vertical movement is concerned, and owing to this fact the traction rope or cable serves in a lmeasure to support the load at a point intermediate the supports e. Of course when the gripping mechanism is passing one of the sheaves F the tractioncable will be raised therefrom; but as soon as the carriage and its attendant parts have passed a short distance from the support the traction-rope will again rest upon the sheave.

Any swinging movement of the bucket in the direction of the length of the cables will not aect the gripping mechanism orvcause the carriage to bind upon the carrying-cable, as the outer frame or casingN will swing upon its supporting-pin O and the gripping mechanism carried by the shell or casing P will rotate within said outer frame N. The gripping mechanism being close to the carryingcable, the degree of movement of the parts at this point is relatively small in proportion to that which may take place in the bucket or at the lower end of the hanger. So, too, any lateral movement of the bucket and frame will not materially affect the cables or their relation one to the other.

Having thus described my invention, what I claim is- 1. In a carriage for cable-tramways, the combination of a body portion, formed of a single casting provided with two arms at each end thereof; fixed axles extending across between the ends of said arms; and a sheavewheel mounted upon each of said axles intermediate the arms.
